Hello, I am a new member here. Last November I recently obtained my male betta fish, Chuck Norris, and since it's been really great up until now. Something devastating has happaned to my tank. I own a 6 gallon Fluval Edge and since cycling it back in December my Betta has thrived. I was a little worried because of the little opening but he's smart and seems to dart up there either for food or air. Through the last several months I've added a few neon Tetra and a moonlight gourami (Chuck ignores them all).
A week ago i was away for two days and I asked my sister if she could drop down and check on them and feed them. She said that the water was a tad cloudy and i told her add a little of the Seachem Clarity. Came home and the water was straight orange. I was confused so I asked her how much she added in - she said what the bottle said. Turns out she added a capful when really she should have added slightly lesser than half a cap. I couldn't even see the fish in there but I decided to wait it out. Morning after, all Neon Tetra and moonlight Gourami died.. pale.. Then Chuck, his face was pale and white but body had color. This was the morning before work So i didn't have time to do maintenance but i was devastated to find all my fish dead. After work and class I came home to find Chuck with color back in his face swimming???! I was shocked because I was pretty sure he had died!! I even poked him this morning because he was on the corner opening of the Fluval edge, no movement just pale in the face. I quickly put him in a large cup and added some betta fix. I cleaned the entire tank and gave it a 80% water change. I even took out the decorations and wiped them clean. I knew it was going to re cycle the tank by doing all that but I didn't want take the chance. I even rinsed the filter, the Seachem Clarity overdose made the filter straight muddy orange... I waited 24 hours and I put Chuck Norris back in. For a week I've been closely observing him, and he seems to be back to normal. Only thing I left in the tank were the two live plants and i put back two decorations plus the heater stayed in there. I don't understand what happaned to Chuck. Did he die and came back to life? Do betta fish have something where if their life is in danger their bodies shut down until the atmosphere is suitable? His face was literally pale, eyes whited over, not moving, even after a nudge with my finger. He just had color in his body and fins. Just want this mystery solved... thank you.
